FALCON High Flow
Technical description
Design
• The FALCON HF consists of two parts: an outer cone
with rubber ring sealed-fitted spigot and an aerodynamically designed outlet cone. NOTE! Size 500 is
delivered without a rubber seal ring.
• As standard the outlet cone is manually operated
when changing the spread direction.
Materials and finish
• The entire air diffuser is made of sheet steel and its
interior and exterior surfaces are painted in our standard
white colour: RAL 9003/NCS S 0500-N.
• Alternative standard colours:
-RAL 9010, white
-RAL 9006, white aluminium
-RAL 7037, dusty grey
-RAL 9007, grey aluminium
-RAL 9005, jet black
• Non-painted and other colours upon request.
Accessories
Electrical motor
• 2 point regulation to change the spread to horizontal/
vertical direction.
Control unit for switching from cooling/heating
• VHC control unit switches the mode of motor controlled air diffusers, intended for both under-tempered and
over- tempered supply air. The controlling parameter
is the temperature difference between supply air and
extract air.
Installation
• Secure the inlet spigot to the connecting duct using
blind rivets.
Maintenance
• The air diffuser can be cleaned, if necessary, using
lukewarm water with dishwashing detergent added.
• Alternatively by vacuum cleaning using a brush nozzle.

Sizing
air supply. A throw of l0,2 is provided for all Swegon's air
diffusers.
• The diagrams provide data for a FALCON HF placed in
a ceiling.
• The sound level is given in dB(A) for products in rooms
and applies to rooms with 10 m² equivalent sound
absorption area (normal acoustic absorption of 4 dB).
• Throw length l0,2 is measured at isothermal air supply.
• Recommended max. permissible temperature below
room temperature is 10K.
• The dB(C) value is normally 6-9 dB higher than the
dB(A) value.
Sound data - explanation
The sound level is given in dB(A) for products in rooms and
applies to rooms with 10 m² equivalent sound absorption
area. Any exceptions are given in the product description.
Measurement of air diffusers according to ISO 5135 and ISO
3471, which is intended for broad-band sound of a stable
nature is performed according to the so-called "Comparison method", which means that the measured effective
sound power level is compared with the sound pressure level
for a calibrated sound source with a known sound power
(method II and ASHRAE 36-72).
The values given in the engineering graph apply to
isothermal supply air.
For air diffusers, the throw is given for mounting facing
the ceiling. Some supply air diffusers can be mounted free
hanging or suspended from the ceiling, in which case the
throw is reduced by approximately 20%. "Free-hanging"
means that the diffuser outlet is at least 400 mm from
the ceiling.
For calculating the width of the air stream, air velocities
in the occupied zone or sound levels in rooms with other
dimensions, please refer to our ProAir web calculation
software available for download at www.swegon.com.

Engineering graphs - explanation
LA
= Sound level in dB(A) according to normalised
frequency weighting A. All sound levels are related
to an equivalent absorption area of 10 m2 (acoustic
absorption of 4 dB)
General
DL
= Sound attenuation in the octave band (dB)
KOK
= Correction for calculation of LW value from the L A or
LWtot values
Unless stated otherwise, the engineering graph for each
product provides the following information:
•

•
Sound level L A dB(A) or LWtot dB can be divided into octave
bands using the correction factor KOK. This is given in table
form for each product.
Formula:
Data for isothermal conditions
Throw with an end velocity of 0,2 m/s
Sound level L A dB(A) 10 m2 equivalent sound absorption
Pressure drop pt, Pa
Air flow q l/s and m3 /h
Pressure drop
LW = L A + KOK
The sound data divided into octave bands is also given in table form. For products with a sound level reported in dB(A)
the opening attenuation is included in the sound attenuation data.
Calculation software
Refer to Swegon's calculation software ProSelect for data
regarding sound in the octave band and sound attenuation in the octave band.
Airflow
The airflow is given in l/s and m3 /h, and is listed in the
engineering diagram for each product.
In the engineering graph for air terminals the pressure
drop is given as the total pressure drop (pt). The total
pressure drop (pt) is the sum of the static pressure drop
(ps) and the dynamic pressure (pd) over the air terminal.
Supply air:
pt = ps + pd
For a supply air terminal the total pressure drop is the
sum of two positive pressures and therefore has a larger
numerical value than the static pressure drop. For extract
air terminals the static pressure drop is negative and the
total pressure drop is therefore a numerically smaller value
than the static pressure drop.
Extract air:
pt = (-ps) + pd
The dynamic pressure is calculated as follows:
Throw length
Testing method according to EN 12238.
